PIPE-HANGER.

To all whom it may concern Beit known that we, LEWIS A. CARPENTER and RICHARD MIDDLETON, citizens. of the United States, and both residing in Revere, county of Suffolk, and State of Massa chusetts, have invented an Improvement 1n Pipe-Hangers, of which the following description, in connection with the accompanying drawings, is a specification, llke letters on the drawings representing arts. J 3?, .This invention relates to a pipe hanger and has forjits object to provide a simple and efficient hanger capable of being quickly and easily adjusted to adapt it to pipes which are to be supported at diflerent distances from the ceiling, wall or other support. To this end, the hanger is provided with pipe engaging members, and one of said members carries a clutching device by means of which the pipeengaging member may be clutched of secured to a supporting member.

The clutching device may and preferably will be made as a tube or sleeve split at one end and capable of being inserted into a hollow stem or tube constituting a supporting member, and of being expanded therein by means of a tapered nut movable on a threaded rod, as will be described. Provision is also made for enabling the pipe engaging members to be secured together with the least possible trouble on the part These and other features of the operator. of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is an elevation and section of a pipe hanger embodying this invention. Fig. 2, an enlarged view in section of one of the pipe engaging members and the clutching device shown in Fig. 1. Fig. 3, a detail of the cooperating pipe engaging member. Fig. 4, a section on the line 4:, 4, Fig. 1, and Fig. 5, a detail to be referred to.

Referring to the drawing a, 6, represents two pipe engagingmembers, preferably of sheet metal and of the construction herein shown. substantially at its longitudinal center, a metal sleeve or tube 0 provided at its free end with one and preferably with a plurality of slits cl extended but partially the length of the same. The unsplit end of the sleeve 0 is secured to the pipe engaging member 6, which may be accomplished in Specification of letters Patent.

The member I) has secured to it Patented Nov. 2, 1915.

Application fiIed April as, 1912. Serial No. 693,205.

any suitable manner, but preferably as herein shown, by providing the sleeve with a reduced end portion 10,,see Fig. 5, which is extended through an opening in the member b and is expanded to engage the said member on its inner side, see Fig. 2, and firmly clamp or look said member against a shoulder 12 formed on the sleeve 0 by the reduced portion 10.

The split end of the tube has cooperating with it an expanding device, herein shown as a nut '14 having an externally tapered surface 15, which engages the inner surface of the split end of the sleeve or tube a, said nut being mounted on a threaded rod 16 having a head 17, herein shown as a screw head, which is capable of being turned by a screw driver. By holding the member Z) in one hand, the operator can turn the threaded rod 16 by means of the screw driver or other tool, so as to cause the nut 14 to travel longitudinally on the threaded rod in opposite directions. The sleeve 0 is inserted into a hollow supportingmember or tube 20, which is designed to be fastened to the ceiling, wall, or other support 21 by a screw 22, having its head in engagement with the walls 23 of an opening formed by reducing the diameter of the tube 20 at one end. The tube 20 may and preferably will be secured to a suitable base plate 25, which is eflected as shown in Fig. 1 by extending the reduced end 24 of the tube 0 through a hole in the plate 25 and expanding the projecting end of said reduced portion.

The split tube 0 in its contracted condi tion is capable of being readily slipped into and moved longitudinally in the hollow stem or tube 20, so as to position or adjust the pipe engaging member 6 with relation to the support 21, and when the member 6 is properly adjusted or positioned, it may be firmly secured in such position by the plunger or other operator turning the threaded rod 16, so as tomove the tapered nut 14% into the split end of the sleeve 0 and expand the split end of the same into firm engagement with the hollow stem or tube 20 and thereby clutch the member 6 thereto.

The pipe engaging members a, b may and preferably will be made of sheet metal, and provision is made for reducing to a minimm; the troubles and labor of the plumber in securing the member a to the member I).

For this purpose, the member I) carries screws 30, which are in threaded engagement with nipples31, formed by elongating the'walls of the openings through which.

the screws are passed and providing said walls with screw threads, and sald screws are and preferably will be enlarged or provided with flanges 32 at their upper: ends, so as to permanently secure the screws to the member 5, whereby the ears 33 of the member a may be provided with slots 34, which are open at their ends, so that the member a is capable of beingmoved sidewise so as to enter the screws 30 in the slots 34, after which the member a can be released by the plumber and allowed to rest upon thehead of the screws 30, thereby leaving both hands of the plumber free to turn up the screws so as to fasten'the member a to the member be broughtclose to the base plate 25.

7 Claims: 7

1. In a pipe hanger, in combination, a

sheet metal pipe-engaging member'having a substantially central opening, a metal sleeve having a reduced end portion extended through the said opening into the pipe-engaging member and expanded within the latter to lock the saidsleevefto the pipe engaging' 'Inember, said tube' being slitted at its free end, a tapered nut. co

operating with thesplitend of said sleeve,

a threaded rod extended from within the pipe-engaging member into said sleeve to engage said nut and having a head within the pipe-engaging member bearing against the expanded end ofthe sleeve within the pipeengaging member, and a hollow stem into which the split sleeve is inserted} and-expanded into contact therewith, saidhollow stem having an internal shoulder at its rear end, for the purpose'spec'ified.

- '2. In a pipe hangeryin combination, a

pipe-engaging member-provided with. a substantially central opening, a metal'sle'eve eX- Y tended outwardly from said member in line with said opening and slitted at its free end,

means to secure thesaid sleeve to the'pipeengaging member to be handled as one, piece,

a rod provided with a head at one end and withscrew-threads at its opposite end, said rod being extended from within thev pipeengagingmember into the split 'sl'eeve and I having its head within the pipe-engaging member, a tapered nut engaging the threadedend of saidrod, and the split end of said sleeve, a hollow stem into which the split sleeve is inserted, and: means to securesaid hollowstem in fixed position with relation to the pipe to be supported, substantially 'as .described.

In testimony whereof, we have signed our namesto this. specification in thepresence of two subscribing witnesses.
